Hello Friends..

I am using liferay version. I am using Eclipse IDE. I am creating maven project from terminal using Maven(Liferay Plugin Project) and then import in Eclipse.
I am easily working with in it. And also import Portlet Struts project also.

But when I am adding dependency of like this...


<!-- Struts 2 + Spring Plugins -->
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-spring-plugin</artifactId>
<version>2.1.8</version>
</dependency>



Tomcat in Liferay is not accept this.. and also nothing to display in Liferay server. All work goes down.. How can I do it??

1. You stop using Maven until it is officially supported by Liferay.
2. You download the ant-based SDK.
3. You create a portlet project in the Liferay IDE.
4. You edit liferay-plugin-package.properties file to pull in the necessary jar dependencies from Liferay.
5. You build and deploy your plugin successfully, and then you realize the problem was your fault by trying to use Maven.
